Part Number: DRV8308 Hi Team,
Customer does brushless motor closed-loop debugging. The customer has debugged two kinds of motors, one motor has 2 pairs of pole pairs, and the other motor has 4 pairs. It is smooth to debug the motor with 4 pairs of poles…
Part Number: DRV8308 Hi,
I was looking for a way to restart the motor before it completely stopped spinning.
As one of the methods, the Hall element is used in the motor, but an external switch is installed in the power line of the Hall element and the…
Part Number: DRV8308 Other Parts Discussed in Thread: STRIKE For the second time during debugging it seems the DRV8308 5 Volts regulator burned out.
It seems it burns out at power up. The enable pin is pulled-up to VM with a 10K resistor and 5V zener…
Part Number: DRV8308 Other Parts Discussed in Thread: CSD88537ND Hi everyone, second post.
I am currently in the process of designing a BLDC motor driver. I did ask another (unanswered as of posting of this question) question about this motor driver for…
Part Number: DRV8308 Hi,
DRV8308 stops communication via SPI after ENABLE signal is aplied (PWM mode). I have to restart driver and it starts communication again.
I did check voltages against Your Dev KIT and they are the same (like VCP, VREG, and VINT…
Part Number: DRV8308 Other Parts Discussed in Thread: DRV5013 , DRV8306 Hi everyone,
I'm pretty new to this entire thing so please be forgiving ;)
I was going to start some designs regarding the DRV8308 but got stuck. I'm not too sure how I'd go about…
Part Number: DRV8308 The motor is a single pole, 57000 rpm with hall effect sensors. The motor is capable of ramping in speed at 400rpm/ms. If I change speed in small incremental steps, there is no problem, but if I make a 50% step the motor will not…
Part Number: DRV8308 We recommend adding resistor between Vreg or Vsw and hall sensor.
Have we seen damage to hall sensors without this resistor in place?
Thanks,
